SPEClFIC'ATION forming part of Letters Patent No. 320,163, dated June 16, 1885.

Application filed January '2, 1885.

.Z'o (LZZ whom it may concern:

Be it known that I, \VILLIAM ORR, of Trenton, in the county of Mercer and State of New Jersey, have invented new and useful Improvements in \VireCloth Lathing, of which the following is a specification.

XVirecloth lathing as heretofore made has presented certain objections and difficulties in its use, which with my improved lathing I hope entirely to remove. Heretofore it has been very difficult to tighten the lathing sufficiently to lay on the plaster. Indeed, when the studding or floor-joists are spaced to their usual distance, pieces ofwood have to be fitted between the studding,and furring-strips nailed to the floor-joists, so as to make a bearing for the lathing each nine to twelve inches, and even then the spring of the cloth is troublesome to the plasterer. When used on brick walls, also, fnrring-strips have to be used, or distancing staples driven into the mortar to allow of an air-space between the bricks and plaster, and then the objection of its springing exists, unless, as before, the distance is made very short between the bearings. This makes considerable expense to the builder, both in the matter of lumber, nails, staples, and time.

The object ofmyinvention is to make wirecloth lathing stiff enoughin itself to withstand the pressure of" the plasterer when applying the plaster without its springing enough to interfere with the laying of it on, and that can be used directly 011 studding, floor-joists, brick walls, or plank or board ceilings or partitions without the use of wood fnrringstrips or intermediate pieces of wood between the studding or floor-joists, and which will set the face of the lathing at sufficient distance from wall, or whatever it is attached to, to leave an air-space between them and the plaster. I accomplish this object by introducing between the meshes of the wire-cloth strips or bars of metal, as shown in Figs. 1, 2, and 3. Fig. 3 shows a section of the solid bars inserted or woven between the warp and filling. This kind of stiffening is more particularly adapted to long-distance bearings, where the studding or beams are wide spaced, or for bending into irregular shapes, 01' for cornices to avoid the expense of putting up iron brackets, usually (No model.)

put up to give stiffness to the wire-clothlatlr ing in such places. These bars extend from edge to edge of the wirecloth, so that the whole width is stiffened by them, and they can be of other shape than square or round; but these are preferable, as they can be bent into curves and for cornices readily, and they can be more easily obtained. Fig.3 shows them woven in so as to leave equal projection on each side of the wire-cloth, which adapts the lathing to this purpose. By a peculiar process I accomplish the result shown in Fig. 1that is, to throw the projection all on one side, leaving the other smooth and level with the rest of the face of the cloth. This kind is more particularly adapted to common uses, and can be attached to brick walls, floor-j oists, or studding without the use of furring-strips, as it forms of itself a sufficiently stiff lathing to support any weight of mortar that may be applied. It is offset by these strips or bars, so as to leave sufficient space between itself and whatever it is attached to, to allow the mortar to clinch over every part of its surface, and to leave aslight air-space, if required, between the mortar and brick walls of a build ing, so as to avoid dampness from moisture in the bricks. The stiffeners for this I make of thin metal, and they may be bent into any shape that will give them sufficient stiffness. Iprefer the V shape on account of obtaining the best results from the least amount of stock and weight; but I can use them in U, threesided, open, square, or round or square tubular shape. \Vere any of these others used, they would occupy relatively the same position; but the form of the warp-wires passing over them would of course conform to the shape of the strips used. I can use solid bars in this connection, as well as strips made from thin metal; but they would add greatly to the weight and cost of" the lathing without pro portional benefit.

Fig. 2 illustrates the method of fastening the stiffened wire-cloth lathing to the walls or ceilings, which may be by staples, as at B, or by nails with washers under their heads, as at O. The staples are made to embrace one or more of the longitudinal wires, and are driven through the stiffeningstrip into the mortar or wood, drawing with it as it descends into the ICO ' set.

open side of the strip the wires which it em-' braces, thus taking up all the slack which may have been left in the lathing after it has been stretched into position. If nails are used, the washers are made to cover two or more wires, as above, with the same results. The method of fastening the lathing, if solid bars bars are used, would be a little different. In that case the staples would not go through the rod, but one side of it or embracing it. It will be seen that this stiffened lathing can be stretched to its place like ordinary wire lathing', without danger of drawing the offsets made by the stifiening-pieces out of shape, as only a part of the longitudinal wires follow the off- The rest, passing in straight line under the base of the strip,pre vents any give at those places when the lathing is put under strain.

At A, Fig. 1 of the drawings, I show a section of the metal stiffening-strip in the simplest and best form in which it can be used,

' both as regards stiffness and lightness; but, as

above stated, I can obtain good results from other shapesas, for instance, by using strips bent into U or open square shape, and inserted or woven in, with the open side next to the body of the wire-cloth, as in the case of the V-shaped strips shown. I obtain a fiat base of some width to rest-against the bricks or studding, which would in some cases be preferable to the sharper point of the V-shaped strip. In cases where extra stiffness is needed to bear heavy strains, the square or round tubular shape could: be used to advantage.

I make no claim to these strips or rods as supports for wire-cloth lathing. They are not put up independently of the wire-cloth, but are incorporated with it, and the stiffened wire-cloth lathing is put up and fastened at one operation and by the same fastenings.

NVhatIclaim, and desire to secure by Letters Patent, is

,7 V 1. Wire-cloth lathing combined with stiffening strips or rods inserted at intervals between the weft and warp wires thereof, substantially as described.

2. The combination, with wire-cloth lathing, of stiffening strips or rods inserted atintervals between the weft and warp Wires thereof, and forming a-smooth surface on one side and projections on the other side of the wire cloth lathing, substantially as described.
